United Airlines Software Engineer Interview Guide

We've seen United lean heavily on resume-specific depth rather than abstract algorithmic difficulty. Multiple candidates reported that interviewers kept circling back to past projects, listed skills, and the exact technologies on their CVs, which means the real test is whether you can explain not just what you built, but why you made those choices and how you’d defend them under scrutiny. One candidate even described the conversation as broad but tied tightly to their background, with the interviewer probing for deep knowledge of whatever was claimed on the resume.

A recurring theme is that United seems to care about practical engineering judgment more than flashy technical breadth. Candidates were asked about SDLC, code quality, testing frameworks, OOP basics like polymorphism, and simple coding tasks such as reversing a linked list. That mix suggests they want engineers who can speak clearly about maintainability, development process, and core CS fundamentals without overcomplicating things. The strongest signal from the experiences we reviewed is that the company rewards candidates who can connect their experience to real software decisions, not just recite concepts.

We also noticed that the interview experience itself can feel uneven, with one candidate calling out repeated reschedules and a lack of momentum. That doesn’t change the technical bar, but it does mean candidates should be prepared for a process that may feel less polished than the role deserves. In practice, the people who seem to do best here are the ones who stay crisp, consistent, and specific when talking through their work, because United appears to be listening for whether your resume reflects genuine ownership.
